Abstract: | A data set of the holiday destination choices of German tourists is segmented using phase in the life cycle; second, holiday motivation and holiday activities and third, the region of residency. For each segment demand is estimated using data on environmental and economic characteristics of countries. The optimal temperature, where demand peaks, ranges from 22°C to 24°C across the segments. More interestingly, the steepness of the temperature demand relationship is different for different segments. Even though the temperature optima are similar, changes in temperature, for example caused by climate change will have a larger effect on demand depending on the steepness of the temperature-demand relationship. A climate index is calculated for each country using climate data and the respective coefficients from the estimated demand equations. The climate index values are different across the segments: the segment containing those tourists who were swimming and sunbathing while on holiday has the highest index values of all of the segments. |

Abstract: | Mainstream research on boards of directors has been focusing on a direct relationship between board characteristics and firm performance, but up till now the results are inconclusive. Although these studies revealed interesting and useful insights, little is known about the factors that shape board effectiveness. This paper aims to reduce this gap by exploring the variety of indicators that contribute to the effectiveness of boards. The paper derives from an interview-based investigation among 104 directors of Belgian listed companies. The findings are further elaborated with quantitative data from two written questionnaires, involving directors of non-listed companies and experts in the field of corporate governance. The results point to three major issues. First, there appears to be a gap between a limited number of structural board measures consistently found in literature and the systematic occurrence of a set of behavioural criteria of board effectiveness in the perceptions of (Belgian) directors. Second, the findings suggest that the value of independence may be overemphasized at the cost of the broader issue of diversity. Third, it appears that mainstream board research ignores to a large extent two additional conditions (the information flow and the leadership style of the chairman) under which a board of directors can make an effective contribution to the strategic direction and control of a company. Our findings suggest that the ambiguity found in current research evidence can to some extent be attributed to the ignorance of a wide range of interconnected structural (such as diversity and competence) and behavioural factors (such as trust, attitude, norms and conduct) which actually shape the effectiveness of boards in performing their roles. |

Abstract: | A multi-agent model of travelers competing to utilize a roadway in time and space is presented in this paper to illustrate the effect of congestion and pricing on traveler behaviors and network equilibrium. To realize the spillover effect among travelers, N-player games are constructed in which the strategy set include (N+1) strategies. We solve the discrete N-player game (for N less than 8) and find Nash equilibria if they exist. This model is compared to the bottleneck model. The results of numerical simulation show that the two models yield identical results in terms of lowest total costs and marginal costs when a social optimum exists. |
